IMPROVEMENT IN MACHINES FQR ATTACHING PAPER-FASTENERS.

Specification forming part of Letters Patent No. 207,157, dated August20, 1878; application filed January 19, 1878.

To all whom it may concern:

Be it known that 1, CHARLES W. BLAKE, of Lyndon, Osage county, and Stateof Kansas, have invented a new and Improved Machine for AttachingPaper-Fasteners, of which the following is a specification:

In the accompanying drawings, Figure 1 represents a verticallongitudinal section of my improved device for attaching paper-fasteners. Figs. 2 and 3 are, respectively, a bottom view of the upper orhammer part, and a top View of the lower or bed part; and Fig. 4

I is a front view of the machine, shown in the act of splitting orspreading the fastener.

Similar letters of reference indicate corresponding parts.

The invention relates to a machine for attaching paper-fasteners,particularly the wellknown McGill fasteners.

The invention consists of a machine made of a spring portion, carryingat the lower or base part a guard for the paper, and a bedplate withrear recess for the slitting-knife and front groove or seat for thefastener, and at its top part the slittingknife, hammer-plate, andspreader.

By referring to the drawing, A A represent the main part of my improveddevice for attaching brass paper-fasteners to the sheets of paper to beconnected. The main part A A is made of V shape, of suitable springmetal, so that the upper or top part, A, is readily raised from thelower or base part, A, after being depressed. The base part, A, isprovided with a bed-plate, B, and the top part with a hammer-plate, B,which fits upon the bedplate.

Back of the bed-plate B is arranged a wire guard, D, against which thesheets to be fastened together are first placed and pushed until theedges of all the sheets rest against the The top part of the wire guardis bent forward at right angles, as shown in Fig.3, and bears on the topof the paper.

A fixed slitting or cutting knife or blade, 0, of the top part Apierces, when the top part is brought down, a hole through the paper aconvenient distance from the edge. The guard D serves both forregulating the distance of hole or slit from the edge, and forpreventing the paper from sticking to and rising with the blade. Theblade 0 enters a recess, 0, at the rear part of the bed-plate B, afterpassing through the paper. An ordinary brass fastener, f, is then pushedthrough the hole of the paper, and its upper upright part placeddirectly below a V-shaped splitter or spreader, E, at the front end ofthe hammer-plate B, while the base or T of the fastener rests in a frontgroove 0r seat, F, of the bed-plate. 4 By pressing the spreader E downits edge passes into the split end of the fastener f, and forces thesame open by bending or spreading the fastener, as shown in Fig. 4.

The spreader E is provided with a front guard-plate, E, which preventsthe top or point of fastener from slipping forward when the spreader ispressed down upon it. The fastener is next placed on the bed-plate, and,by a short blow upon the knob G of the top part, is laid over the paperin a neat and firm manner.

The bed and hammer plate are made perfectly flat, so as to flatten thefastener in the same manner as by the hammer and bed plate at present inuse.

The spring-part A A may be made of spring brass, iron, or steel, and thedevice finished in suitable manner, forming a convenient machine forapplying these brass fasteners in quick and neat manner, without thetroublesome opening of the fastener by hand, and without requiringseparate tools for piercing of the paper and clinching of the fastenerends, which tools are thus combined in one simple, convenient, andtime-savin g implement.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1. A machine for attaching paper-fasteners,consisting of a spring-frame having a top part, with a hammer-plate,fixed slitting -blade, a spreader, and a base part, with a bed-plate, awire gage-guard, and groove or seat for the fastener, all arrangedsubstantially in the manner described, and for the purpose specified.

2. The combination of the bed-plate B ,having rear recess, 0, and of thewire safeguard D, with the slitting knife or blade 0 of spring acted toppart, A, substantially as specified.

3. The combination of the bed-plate B, having groove or seat F for thefastener, with the hammer plate B, spreader E, and front guard, E,substantially as specified.

CHARLES WILLIAM BLAKE.
